HYDROCARBON-VAPOR STOVE.

SPECIFICATION forming part of Letters Patent No. 623,7 29, dated April 25, 1899.

Application filed April 4, 1898. Serial No. 676,853. (No model.) i

To all whom it may concern:

Belt known that I, EDWIN G. MUMMERY, a citizen of the United States, residing at Detroit, county of \Vayne, State of Michigan, have invented a certain new and useful Improvement in Hydrocarbon Vapor Stoves; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Mypresent invention is designed to provide certain new and useful improvements in hydrocarbon-vapor stoves; and it consists of the construction, combination, and arrangement of devices hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure l is a view in perspective. Fig. 2 is a vertical cross-section on the line 2 2, Fig. 1. Fig. 3 is an enlarged detail view of a burner and adjacent parts in section on theline 3 3, Fig. 2. Fig. 4 is aview in elevation showing a modification in the construction of the burner. Fig. 5 is a vertical cross-section on the line 2 2, Fig. 1, on an enlarged scale, illustrating the construction of the burner disclosed in Fig. 4, Figs. 4 and 5 being on an enlarged scale. Fig. 6 is an enlarged detail view showing means of supporting the burner upon the base D.

The leading feature of my invention refers to the arrangement of the warming-closet or warming-oven and the relation of a hydrocarbon-burner thereto.

I carry out my invention as follows:

A represents the framework of a hydrocarbon-vapor stove which may be of any suit-' able construction and form, the same being provided with a warming-closet or warmingoven 13, a door or doors B affording access thereto. Said warming-closet or warmingoven may be formed in any desired manner. As shown, the ends or sides A of the stove are made of closed metal secured to the frame to form the lateral sides of said closet, the doors B forming the front of the closet and a back wall A forming the rear of the closet. A lower partition A forms the base of the closet and an upper partition A forms the top of the closet. Above the warming-closet is an open chamber immediately beneath the top of the stove, in which open chamber the burner or burners are located and into which the piping connected with the burners is extended, the open chamber affording ready access to the burner. To form the open chamber, the framework of the stove is preferably left open at the front and at the rear thereof, as shown in the drawings.

C denotes one or more hydrocarbon-vapor burners of any suitable construction.

I do not limit myself solely to any particular construction of the burner. The burner shown in Figs. 2 and 3 conforms in its general construction to the form of burner embodied in a patent of the United States granted to me January 19, 1897, No. 575,659, such a burner being a very suitable burner for use in connection with my improved warmingcloset, although such a burner maybe modified in its construction, if desired, in certain of its features. The burner herewith shown in Figs. 2 and 3embodied in the patent above referred to consists, essentially, of a channeled base 0', constructed with an interior orifice or opening 0 therethrough, through which air may pass upward within an inner foraminous wall 0 which is shown provided with an inwardly-projecting cap 0 perforated at the center and provided with a depending tube C opening through the cap. I do not, however, limit myself solely to a burner having an inner foraminous wall provided with an inwardly-projecting cap. A flaring tube might take the place of the cap, as embodied, for example, in an application filed by me March 23, 1898, Serial No. 674,875.

C denotes an outer foraminous wall spaced from the wall 0 and forming a combustionchamber between them above the vaporizingchannel of the base 0'.

C denotes an outer drum which is made non-foraminous except at the top thereof, the top 0 projecting inward and formed with a series of perforations. The drum C is spaced from the outer wall C forming an air-cham her 0 between them.

In Figs. 4 and 5 a burner is shown analo- Ice gous in most respects to a hydrocarbon-generator embodied in United States Letters Patent No. 568,956, issued to me October 6,1896.

The burner illustrated in Figs. 4 and 5 is constructed with a base Q, having double vapor-generating channels'I'I and II, said channels being concentric, the inner channel formed with an opening h therewithin, the base being formed with an additional opening h between said channels through which air may be admitted to the comlmstion-chambers H and 11 above the channels of the base, respectively. The inner channel II is formed with upwardly-pro jecting flanges 1 and 2, while the channel 11' is constructed with upwardly-projecting flanges 3 and 4. Upon the flange 1 is a foraminous wall 5, which may be formed with a cap 6. Upon the flanges 2 and 3 are foraminous walls 7 and 8, which maybe connected with a cap 9 at the top thereof, while above the flange 4: is a foraminous wall 10. A drum 11 surrounds the wall 10, said drum formed with an inwardlyturned flange 12 at its upper end, which may be perforated, as shown at 13, said drum forming an airchambcr 14 between it and the outer foraminous wall 10, said chamber 14 open at its lower end. The burner shown in Figs. i and 5 may be supported in any suitable manner upon the partition A" of the oven.

In Figs. 2 and the foraminous walls are shown made of perforated metal.

In Figs. 4 and 5 the foraminous walls are shown made of kerfed metal, said walls in the latter case being preferably made of cast metal and kerfed after being cast. The upwardly-projecting flange 4 of the base Q is shown formed with a series of perforations 15 to admit air into the vaporizing-channel II below the foraminous walls.

Bot-h burners are shown supported upon a hollow support D, said support opening through the partition A forming the top of the closet, and preferably projecting downward slightly within the closet, as shown. This support may be supported upon the partition A in any suitable manner. Thus, for example, said support may be shouldered or flanged, as shown at (Z, to restupon the partition A. The burner may be engaged upon the support D in any suitable manner. Thus, for example, the support D may be formed with inwardly-projeeting ears (1, engaged with corresponding ears 0 upon the base of the burner. The outer drum of the burner and the hollow support D are arranged so as to admit air to the burner from beneath the partition A, air being admitted through the support from the oven in any suitable manneras, for example, through inlet-orifices a in the rear wall of said closet. As so supported and arranged it will be evident that when the burner is in operation heat will be directed through the opening oropenings in the base of the burner downward into the warming-closet B. The cap or caps of the foraminous walls or analogous device will serve obviously to check the upward passage of the heat and to direct the heated air downwardly within the chamber or chambers inside the foraminous walls, while the top of the outer drum will also serve to check the upward passage of the heated air in the outer air-chamber and to direct it downward through the support D into the closet B. Little or no air, it will be seen, enters the burner to support combustion above the partition A and it follows that the air heated within those chambers finds little or no opportunity to escape therefrom, except by being diverted downward into the said closet or by passing upward through the perforated covers or tops of said chambers, so that there will always be a suificient deflection of heated air into the closet for purposes for which such a closet is employed. The outer drum of the burner may not, however, be so closely fitted to the support D as to exclude air altogether from entering the burner thereat.

E represent-s any suitable arrangement of supply-pipes communicating into the channeled base of the burner from the supplytank F.

It is evident that the tubular or hollow support D might be omitted within the scope of myinvention, the burner being otherwise supported at the top of the warming-closet, so as to have the heat passing downward through the base of the burner confined and directed into the closet.

The general construction of the burner as an independent article of manufacture forms no definite part of my present invention, but any suitable burner in combination with other features above described constitutes the invention herein set forth.

As shown in the drawings, a shelf G is engaged upon the frame of the stove, as upon brackets G, said shelf being hinged toward its forward edge upon said brackets, as indicated at g, Fig. 2, permitting said shelf to be folded forward, so that the reservoir may readily be filled.

In Fig. 3, for example, I have shown in dotted lines the partition A located about the outer drum C instead of therebeneath, which form of construction is contemplated in my invention, inasmuch as the essential feature of the relative location of the burner and of the warming-closet is to have the top of the burner above the top of the warming-closet, whether the whole burner be located above the top or partition A of the closet or whether a portion of the burner projects thereahovc, both modifications of construction being indicated in Fig. 8.

The burner being located in an open chamber above the warming-closet, it is obviously necessary in order to properly direct heat from the burner into said closet to so arrange and locate the burner as to confine a portion of the heat generated thereby, so that it will pass downward into the closet. The support D serves this purpose, inasmuch as the base into the closet.

of the burner is thereby surrounded and the heat thereby confined within the support or in an analogous manner to prevent the lateral dissipation of the heat in an open chamber and so confine it that it will be directed Moreover, owing to the location of the burner in an open chamber, were it not for the base of the burner being surrounded or confined so as to prevent the air from the open chamber entering into the innerair-chamber of the burner to supportcombustion the admission of air to the inner chamber directly from the open chamber would effectually prevent the heat being directed downward into the warming-closet.

What I claim as my invention is 1. In a hydrocarbon-vapor stove, the combination of an open chamber immediately below the top of the stove, a warming-closet beneath said open chamber, and a burner within the open chamber constructed to confine the heat passing downward through the base of the burner so that it shall be directed into said closet, said burner and closet constructed to permit the burner being supplied with air to support combustion through said closet, substantially as set'forth.

2. In a hydrocarbon-vapor stove, the combination of an open chamber immediately below the top thereof, a'warming-closet below said open chamber having an opening in the top thereof, and a burner located in the open chamber having an open base adjacent to said opening, said burner constructed to inclose said open base and to confine and restrict the heat passing downwardly through said base so that it shall be directed into the warming-closet, substantially as set forth.

3. In a hydrocarbon-vapor stove, the combination of an open chamber immediately below the top of the stove, a warming-closet below the open chamber, a burner located within the open chamber, and an intervening hollow support supporting the burner at the top'of the closet, said support constructed to restrict the heat passing downwardly through the burner so that it shall be directed into the interior of the warming-closet, substantially as set forth.

4. In a hydrocarbon-vapor stove, the combination of an open chamber immediately below the top of the stove, a warming-closet located immediately beneath the open chamber having an opening in the top thereof, and a burner provided with an open base and with an interior air-chamber, the top of the burner being located in said open chamber and 'having its base communicating with the interior of the closet, the base of said burner being inclosed so that the passage of heat from the burner will be restricted and directed downward therethrough into the closet, and so that the passage of air through said interior airchamber of the burner will be caused to enter said air-chamber through said closet, substantially as set forth.

5. In a hydrocarbon-vapor stove, a warming-closet, an open chamber above the warming-closet, and a burner having its upper portion within the open chamber, said burner constructed to restrict the heat passing downward through the base of the burner so that it shall be directed into said closet, substantially as set forth.

In testimony whereof I sign this specification in the presence of two witnesses.
